Ħal Saflieni Hypogeum

The only structure of its kind in the world

The Hal Saflieni Hypogeum in Paola is the only known prehistoric underground temple in the world. Carved from soft limestone bedrock around 4000 BC, it extends across three levels to a depth of 10.6 metres below ground, covering approximately 500 square metres. It was discovered accidentally in 1902 when construction workers broke through into the subterranean chambers.

A necropolis of 7,000 souls

The remains of approximately 7,000 individuals were found in the Hypogeum, making it one of the largest prehistoric cemeteries in the world. But it is more than a necropolis. The spaces are decorated with red spiral paintings, and the niches and chambers imitate the architecture of above-ground megalithic temples, with carved pillars and lintels.

The Oracle Room

The most mysterious space is the Oracle Room on the second level. This small chamber has a unique acoustic property: a male voice at low frequency resonates throughout the entire complex, while higher-pitched voices do not. Scientists speculate the effect was used in religious rituals, creating the impression that the entire temple was "speaking".
